PATENT (OFFICE EDWARD H. LORENZ, OF WEST HARTFORD, CONNECTICUT, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO HARTFORD-EMPIRE COMPANY, OF HARTFORD, CONNECTICUT, A

CORPORATION OF DELAWARE GLASS-SHAPING MACHINE Application filed August 8, 1921. Serial No. 490,567.

making glassware. The particular embodiment of the invention herein shown and described is for forming bottles by blowing processes, but many features of the invention are susceptible of use with other machines, and for other processes of shaping glassware.

One object of the invention is to provide a new and completely organized machine for shaping glassware, which will rapidly and automatically perform all of the operations necessary to form finished glassware from charges of molten glass.

Another object of the invention is to incorporate certain safety devices in the machine by which it will be stopped in case of abnormal position or operation of its various arts.

A further object is to provide such machines with means for maintaining properregister and timed relation to other machines with which they may be associated, as, for

example, a feeding machine'for delivering charges of molten glass tothe shaping machine. These means include a clutch located in the driving connection between the shaping machine and the feeding machine, or such other associated machine, whereby the shaping machine may be stopped while the feeding, or other associated machineicontinues in operation. Means are also included whereby the shaping machine, when again put into operation, will automatically resume operations inproper'synchronism and time relation with the feedin machine, or other associated machines reiierred to.

The various features of the invention em ployed for the accomplishment of these ob jects and such others as may hereinafter appear, will best be understood from the following description and accompanying drawings, in which Figures 1 to.8 are diagrammatic views illustrating the principal steps in the formation of a bottle by the machine of the present Fig. 10 1s ,a side elevation lookingfromthe i left of Fig. 9

Fig. .11 is a plan view of the lower part of the machine in section taken substantially on the line ll--11 of Fig. 10;

Fig. 12 is a partial plan of the mold carrymg turret, certain parts being shown in section and others broken'away to show the parts below;

Fig. 12 is a detail view projected from Fig. 12;

Fig. 12 is a detail view similar to Fig. 12, but showing only the mechanism for reverting the molds;
